The given statement that Fluoridation of drinking water helped to reduce water-borne infections like cholera and typhoid in the United States holds true

Fluoridation is the carefully regulated addition of fluoride to a public water supply with the sole purpose of lowering tooth decay. Fluoride is added to or naturally occurs in fluoridated water at a level that is beneficial for preventing cavities.  Fluoridated water affects dental surfaces in two ways: in the mouth, it produces small amounts of fluoride in saliva, which slows down the demineralization of tooth enamel and speeds up its remineralization in the early stages of cavities.  In the United States, adding a fluoride substance to drinking water typically costs $1.17 per person per year.

The factory might affect the carbon and water cycle by:

A greenhouse gas is a gas that reflects heat in all directions while absorbing infrared radiation (IR).

The atmosphere of the earth contains greenhouse gases, which absorb solar IR and then emit it.

Along with heat from the sun that has entered the atmosphere, some of the heat emitted makes it to the earth.

The continual flow or movement of inorganic and organic carbon molecules and compounds in the atmosphere and other parts of the globe is known as the carbon cycle.

One of the greenhouse gas's components, carbon dioxide, is what causes the planet's temperature to rise and cause global warming. They significantly trap solar heat, warming the planet's atmosphere.

Because greenhouse gases like carbon dioxide, oxygen, and nitrogen keep the planet's temperature stable, they contribute significantly to global warming.

The PCR amplification process most frequently employs an enzyme known as Taq DNA polymerase.

Taq Polymerase, or Taq DNA  polymerase, is a biological catalyst that helps nucleotides join together to form DNA. Taq polymerase is a protein that is 832-amino acids long and has a molecular weight of 94 kilodaltons. It is a homolog of the Pol I DNA polymerase that is found in Escherichia coli (E.coli) (approx). This enzyme can withstand temperatures up to 95 degrees Celsius for 40 minutes before reaching its half-life. At the ideal temperature of 72 degrees Celsius, the rate of nucleotide incorporation ranges from two to four kilobases per minute.  

Polymerase chain reaction operates at a very high temperature. At this temperature, Taq polymerase is able to carry out its function efficiently.

B: Carbon can form single, double, and triple bonds with other carbon atoms.

The size of the primary transcript in the nucleus of the eukaryotic cell is longer than the size of the functional mRNA.

The primary mRNA transcript present in the nucleus is obtained from DNA template sequence transcription. The primary transcript is said to be inactive due to the presence of some non-functional regions (introns) within.

To obtain a functional mRNA from the primary transcript, introns are spliced or removed from the primary transcript with the help of RNA alternative splicing. This leads to the joining of the functional segments (exons) in the mRNA transcript. This joint segment of exons is the modified active form of primary transcript known as the functional mRNA, which is comparatively shorter in length.

Hence, we can conclude that the size of the functional mRNA is shorter than the primary transcript in a eukaryotic cell.

Explanation:

A line that is decreasing would be a graph of carbon dioxide absorption for this forested area.

Environmentalists made the graph to predict the effect of deforestation on this area over the next 20 years. Due to deforestation, the number of trees will be decreased and hence the carbon dioxide absorption also decreases.

Photosynthesis is the process through which plants take in carbon dioxide from the atmosphere, combine it with water and light, and produce carbohydrates. 

It is commonly known that the rate of photosynthesis rises as atmospheric CO₂ levels rise.

But if the number of trees decreases, then there will be less photosynthesis and that's why carbon dioxide absorption also decreases.

The salivary glands and the mammary glands differ in structure on the basis of their basal epithelial cells.

The salivary glands have branched ducts which open in oral cavity. They also have saliva secreting glandular secretory end pieces called acini. The mammary glands contain alveoli which are lined by epithelial cells that secrete milk. The alveoli group together to form structures known as lobules each of which has a lactiferous duct.

In both these glands, the epithelium gets arranged into alveoli but in salivary glands, a single basal epithelial cell happens to cover the top of each alveolus but in the mammary glands, a number of basal epithelial cells are draped over each alveolus.

Chemotaxis

- movement in response to chemical stimulation

- pseudopods move toward microorganisms at the site of infection

Adherence

- attachment to a microbe

Ingestion

- engulfing pathogen with pseudopodia wrapping around pathogen

- pathogen is placed into a vesicle (phagosome) that contains lysozyme

Digestion

- phagosome maturation

- lysozyme merges w/phagosome>releases digestive enzymes>becomes a phagolysosome

- microbes are usually killed at this point

The hydroponic method involves growing the tomatoes in a nutrient solution which contains all of the essential elements.

The practise of growing plants without the need for soil is known as hydroponics. Flowers, herbs, and vegetables grown hydroponically are planted in inert growing material and are then given nutrient-rich solutions, oxygen, and water throughout the growing process. The use of this technique results in accelerated growth increased yields, and improved quality. When a plant is growing in soil, the roots of the plant are always looking for the nutrients it needs to survive in order to provide for the plant's needs. If the root system of a plant is provided with direct access to water and nutrients, the plant does not need to expend any energy in order to maintain its own life. It is possible to focus the energy that the plant's roots would have spent obtaining food and water toward the growth of the plant instead. As a direct consequence of this, the development of new leaves and the blossoming of fruits and flowers are both stimulated.
